LEY, rcsssnonus ir rs, ASSIGTTGIL TO SAMSON GOEDLAG-E COED-MAKING MACHINE Application filed March 18, 1929.

The invention relates to an improved cordmairing machine and especially to a machine for making braided cord.

A great variety of machines have been devised for making braided cord which for the most part have possessed some particular advantage as advance was made in the art, but I know of no machine rela ively narrow and compactcapable of receiving and operat any large number of heavily lade spools. It is accordingly the object of my invention to provide a n achine having such capability.

Though greatprogress has been made in the art of cord making machines since the days oi": the early machines, yet these early machines possessed many advantages in their essential principles both in point of simplicity of construction, facility of operation and easy maintenance and repair. An ex ample of such machine is shown in the patent to J. P. Tolman, No. 3%,855 or April 9 7, 1886, in which the spools were borne by travelers moved circuitouslyby carrier gears from one position of rest in a holding ring to another position along a looped tracl-z or way. Perhaps the most essential objection to this old machine of the Tolman type, or for that matter to earlier machines of the same genera 1 type, but in which the travelers were governed in their movements by some term of movable switch or selector as distinguished from a looped track, was that only spools of relatively small diameter carrying comparatively little strand could be used without unduly widening the machines espe cially when the number of the spools "as increased, for the reason that the spools would interfere and could not pass one another in the operation oi the machine. It is accordingly a further object of my invention to pr vide av machine of the early type as above referred. to, in point of principle, but one capable of carrying a large number of spools all of relatively large diameter or strand-carrying capacity, and this without increase in the width of the machine.

The invention can best be seen and understood by reference to the drawings in which- Serial side elevation of the machine. section on line 22 of Fig. 1. section on lines of Fig. 2

piece 2 with hearing thereon by means of hinged toot 3 is a stationary center post )rei'erably made hollow in order that a core o may be introduced to pass upwardly through it when the braided cord is being made with a Rising also from the base with bottom ends located within butts (3 thereon are posts '7. These posts are circumterentially arranged, and fixed thereto to lie between them in superposed planes widely separate from one another are internally toothed holding rings 8 and 9, respectively. These rings apart from their normal functions in the operation of the machine, act as braces, rcintorcing the uprights and giving rigidity to the entire machine. In addition to their internal teeth both the holding rings 8 and 9 are provided with spaced notches interposed at regular intervals between their respective teeth, the holding ring 8 being provided with notches 10 and the holding ring 9 with notches 11. These notches are adapted to receive and hold at itervals in the operation of the machine the spool car ying spindles-i borne by the travelers as will later be explained.

Loosely embracing the fixed center post l and rotatable around this post is a vertical sleeve 12. This sleeve has bearing to turn at its bottom end on the centerpiece 2 o'l" the frame and flanged toot 2-3 of the. center post it. At its top the sleeve is contracted to lit snugly around the center post which provides an internal bearing for it.

Fixed to the sleeve 12 with outward extension therefrom to lie bepeath the holding ring 8 is a cam table 13 having a looped traclz or way 14- therein, within which run travelers 15 bearing spindles 16 which carry 'shaft ll extending through the can! frames 17 containing il slrard carrying have to be very thin spools dizuneirically to testing to turn upon the table 1?- are a number of carrier gcain Each of these gears is iixcd to a rotatable v-r-rtical table and held from vertical dil )lacc zcnt by a nut 52:! on the lower end oi the ft with bearing against the under side oi tae cam table. The carrier gears 20 are arran, d in the same plane with the holding ru and the teeth thereof are in mesh witn the internal teeth of this ring so that the rail 31 gears will be rotated as the cam table is turned. Each of the carrier pro vided around its peripheral edge between its teeth at regular intervals with no e s 23 which receive and hold at intervals in the operation of the machine, the spool carrying spindles 16 borne by the travelers 15.

The cam table 8 is turned by means of a pinion gear 25 which engages the toothed peripheral edge of this table. 'lhe pnno n gear 26 is fixed to a vertical shalt Si wluca turns within hubs 2S borne by brackets fixed to the holding rings 8 and 9 respectively, and this preferably through connection with adjacent ones of the posts '7 which support these rings. The shafft l rson its lower end a bevel gear 30 co-opcrat1ng with which is a bevel gear ill carried by a driving shaft turned by any suitable source of power, not shown.

The braiding opention cl' 'ectcd by the movement oi the spools with re (o a central braiding point or die consequent upon circuitous movement oi the travelers 15 through co-operating action ot he cam table, carrier gears and ho ring upon the turning of the cam tabc i ferred to in Letters Patent i\ "ailpl-ll; previously referred to and will. be tuily understood in the light of this patent. liuring this operation the strands 35 oil" the various spools will be directed upwardly through the spindles 16 (made hollow) on whic the spools are arranged, and the; redirected by arms 36 on the top en s ol the rc:--:; cctive spimlles to the braiding point or die This die is borne by a die suppor '73 attachcd to any suitable fixed part of chine.

It will be observed that a relatively number of strand carrying spools l a rge permit of l'lliil' passing one another iii the operation of the machine. (,Trmscqiwntly as t could carry but little strand material would have to be frequently rcplenishwl. cordingly rei'crcncc 'vill now be made to lint phase of the invention which permit; of a large number oi spools oi relatively large diameter and strand carrying capacity beirg opc aled oil? travelers working on the one cam tab without increasing the width of the macl e.

The result .15 initially obtained by making th spool carrying spindles relatively long spindles, and then arranging the spools carried by them in sets lying in separate superposed planes. Three sets of spools are shown in the present example of the machine, l0 representing the spools of the bottom set, ll the spools of the next set above, and l2 the spools of the upper or top set. The further arrangement ol the spools is such that those spools will lie in different sets or planes which are borne by spindles attached to travelers that pass near one another as they traverse during the operation of the machine over the one cam table, thus keeping the spools, which might otherwise engage one another, widely sop-2r: tcd at all times, so that spools of relatively large diameter and strand carrying capacity can be u ed.

inasmuch as relatively long spiinlles are borne by the travelers in, which spindles carry more or less weighty spools. it becomes icccssary that provision be made for supporting and guiding the top ends of the spindles in order that the spindles will be maintained to run true and rigid and not cramp the travelers by which they are carried. An arrangement accordingly is provided at the head of the spindles which in many respects is like that at the bottom. It comprises the internal toothed holding ring 9 provided with periodically spaced notches ll between its teeth as 'n'eviously described. This holding ring is maintained by the posts '7 in precise vertical alignment with the holding ring R at the bottom of the spindles and all the parts of the top ring are in precise vertical alignment with those of the bottom ring including its teeth and respective notches. (fli'ropcrating with the internal toothed edge of the holding ring 9 are carrier gears These carrier gears are precisely like the carrier gears 20 at the bottom of the spindles and are provided with periodically spaced notches 4% between th ir respective teeth for receiving the top endsof the spindles precisely as notches 2 are provided between the teeth of the bottom carrier gears for receiving the bottom ends oi the spindles. The tccth of the top carrier gcars and notches are all precisel in \crtical alignment with those of the bot- 1 t) it).

tom carrier gears. The top carrier gears are fixed to the same rotatable vertical shafts 21 that carry the bottom carrier gears and accordingly turn simultaneously therewith.

Mounted upon the fixed holding ring 9 is an externally toothed cam table which corresponds relatively with the cam table 13 at the bottom of the spindles. The cam able at?) is retained to turn upon the holding ring 9 by means of an annular flange 46 on the under side thereof, which runs within a groove 4 formed in the top side of the holding ring 9. The cam table a5 is provided on its inside with a cam edge as which is precisely like the outer cam edge presented by the looped track or way 1% on the cam table 13, and this cam edge 4L8 on the upper cam table lies in precise vertical alignment at all points with the outer cam edge presented by the looped track on the bottom cam table. Both cam tables are combined to rotate together by vertical shafts 5O connecting the two tables. The peripheral gear teeth on the two cam tables are in vertically coincident alignment. The upper cam table is rotated simultaneously with the lower cam table by means of a pinion gear 51 engaging its toothed edge, and this pinion gear is fixed to the same shaft 27 as turns the pinion gear 25 which drives the lower cam table, both pinion gears 51 and 25 being precisely alike.

Carried by the tops of the spool carrying spindles 16 borne by the travelers 15 is another set of travelers at. These travelers are held in engagement with the cam edge 48 oi' the cam table 15 by means of carrier plates on the heads of the carrier gears a3, and fixed to these gears by pins 56. The carrier plates are like the carrier gears to which they are fixed, being provided with notches 57 vertically coincident with the notches nin the carrier gears 43, but have no teeth. The carrier plates operate through the spindles contained in their respective notches to hold the travelers 5 k in proper engagement with the cam edge as of the cam table 15. Tu fact the carrier plates perform the same relative function in the retention of the travelers 5% with relation to the cam edge 48 presented by the upper cam table as does the inner cam edge to the looped track or way 1% on the lower cam table 13 but the arrangement permits of the spool carrying spindles being extended above the upper cam table to permit of the strands, issuing from the top ends of the spindles, passing to the braiding point.

Thus the spool carrying spindles are retained at opposite ends of the machine to run vertically true and rigid without cramping, and relieving the travelers 15 carrying these spindles of strain which would otherwise come upon them. ther means than that shown, however, may be employed without departing from the essential principles or" my invention. I

Having thus fully described my invention, I claim and desire to secure by Leters Patent of the United States 1.
